It is legal from other countries of EU, but not from USA.In any case, all my current plants are from certified nurseries.I live in a zone without citrus plantations, only isolated plants in gardens. We are limited to the north by the sea and too cold zones for citrus by the south, west and east. The citrus zones of Spain are 700 km away from my zone.

Hi there! I don't think is legal to import budwood as private from outside EU, but seeds are allowed. I'm unsure if xie san is mono or poly however, here it looks like in catalog with its other name of Wakayama.Good luck!
